// Open log in append mode. If it doesn't exist it will be created.
$file = fopen('ua-strings.txt', 'a');

// Append the UA string
fwrite($file, $_SERVER['HTTP_USER_AGENT'].'\n');

// Close
fclose($file);

thank u for u reply. Could tell me how in both php and visual basic app i can change the default string sent to $_SERVER['HTTP_USER_AGENT'] log file? For example if the default is :Microsoft URL Control - 6.00.8862\n

and i want to send this :

Media Player Classic\nMedia Player Classic\nshoutcastsource\nMozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; {BE6B3C18-D43F-BBA3-8046-F416968AB502}; (R1 1.5))\n

Well PHP won't be sending a UA but if you want to do it in VB, you'll want to post into the VB forums.

Most controls for VB have a UA Microsoft created and you'd have to completely write your own control to have a custom UA.

I do apologise. I meant the UA strings to be on separate lines. However I used the wrong quote marks

The second line should be thus:

fwrite($file, $_SERVER['HTTP_USER_AGENT']."\n");
